Lousville's Smith (pictured) may be the most intriguing player on the list. He averaged 22.3 points and 2.5 steals in the Cardinals' six NCAA Tournament games on their way to the title in 2013. He averaged 18.2 points per game last season.

None of these players is projected in the first round, and the Celtics don't currently own a second-round pick, but a lot can happen between now and draft night.
